The root issue is Centurylink has no peering with Hurricane Electric on IPv4, and ditto for peering with numerous other providers, versus on IPv6 they have a much more open peering policy. This seems to be common among a number of ISPs, though as time goes on this issue will hopefully ease.
In IPv6 land, that can introduce a lot of pointless complexity.
It would be reasonable for customers to be able to expect the ability to get /48s or /56s. Instead they don't even get a proper /64.
